To all of you... Don't burn old gas in "ANYTHING" This is something I know something about, As some of you remember I worked at a late model salvage yard for 35 years, I have burnt 1000's of gallons of used gas in my cars and trucks through the years, I've also seen several engine failures through the years from burning old gas, I'm not talking 20 year old gas, some gas was 3-5 years old and looked and smelled fine. The

Old gas can break down and then when burned will leave deposits on the valve stems then after the engine is shut down and cools the valves will become stuck in the valve guides, If the valve is stuck open -you got it, it will hit the piston- game over. if the valve is stuck closed- broken or bent push rods.
I have seen this happen and has happened to me, I lost 2 engines in an old Jeep, both broke valves. I also had it happened in one of my 8n's, some of the valves stuck open but lucky for me being a flat head engine no damage was done, I was able to get the engine running on 2 cylinders, I just let it run for 10-15 minutes til the valves finely freed up and it ran fine- knock on wood !
There's info out there on this subject, didn't have time to look.
